Prostatic cancer is the most common neoplasm occurring in males over the age of 50 years. Radiotherapy is one of main methods of therapy of the cancer. 3D conformal radiotherapy is broadly used for therapy of prostatic cancer in oncological centres all over the world. Various geometries of therapeutic beams are currently used for that purpose. Their task is to deliver the planned therapeutic dose to the area of tumour, with simultaneous minimization of doses reaching critical organs located in the neighbourhood of the lesion. Diversity of beam configurations and available options of the therapy planning systems allow creation of multiple therapeutic plans. In some cases, achievement of a favourable dose distribution in the target volume may affect doses deposited in organs at risk. Therefore the choice of an optimum configuration of beams in prostatic cancer therapy remains unclear.
